Rude Employee can't set up card machine

Can Caltex Linton grange PE please retrain their staff on how to set up the card machines to tap. I don't know the mans name, he was tall, chubby, white and had a beard, he tells me "Everybody knows you can't tap standard Bank cards, give me the name of the person who let you tap before" very rudely. Imagine!!! Standard Bank is partnered with Caltex and I have a titanium card. I've been tapping everytime. He just can't set up the machine. It's Covid times. Nobody should be touching those filthy machines. Please send me an update with training records because that was unacceptable.
